Adds `./cli.py commit [<slug>]` which runs `docker commit` on the active agent container and stores the resulting image tag in per-bottle state. The next `./cli.py resume <slug>` automatically boots from the committed snapshot instead of rebuilding from the Dockerfile, preserving all in-container state across restarts and migrations. - bottle_state: add write_committed_image / read_committed_image helpers - docker/util: add commit_container wrapper around `docker commit` - docker/launch: check for a committed image before the Dockerfile build step; fall back to normal build if the image is absent from the daemon - cli/commit: new command with interactive slug picker; errors clearly on non-Docker backends - 50 new unit tests covering all paths Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

"""commit: freeze a running Docker bottle's container state to a local image.
|
|
|
|
Runs `docker commit <container> <image-tag>` on the active agent
|
|
container and stores the image tag in per-bottle state so the next
|
|
`./cli.py resume <slug>` boots from that snapshot instead of
|
|
rebuilding from the Dockerfile.
|
|
|
|
Only the Docker backend is supported. Smolmachines VMs have no
|
|
container-level commit API in the current smolvm CLI surface.
